Change the program to have a more consistent return code. Specifically,
do not make bpftool return an error code simply because it reaches the
end of the list of the eBPF programs to show.

Make print_hex() able to print to any file instead of standard output
only, and rename it to fprint_hex(). The function can now be called with
the info() macro, for example, without splitting the output between
standard and error outputs.

Program tag is usually displayed as string of bytes without
any separators (e.g. as "aa5520b1090cfeb6" vs MAC addr-like
format bpftool uses currently: "aa:55:20:b1:09:0c:fe:b6").
Make bptfool use the more common format both for displaying
the tag and selecting the program by tag.
This was pointed out in review but I misunderstood the comment.

Compile the instruction printer from kernel/bpf and use it
for disassembling "translated" eBPF code.

Add documentation for bpftool. Separate files for each subcommand.
Use rst format. Documentation is compiled into man pages using
rst2man.
